General annotation (Comments)

Function	Appears to have a function in striated muscle development and regeneration.
Catalytic activity	2-phospho-D-glycerate = phosphoenolpyruvate + H2O.
Cofactor	Magnesium. Required for catalysis and for stabilizing the dimer.
Pathway	Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 4/5.
Subunit structure	Mammalian enolase is composed of 3 isozyme subunits, alpha, beta and gamma, which can form homodimers or heterodimers which are cell-type and development-specific. In vitro, interacts with several glycolytic enzymes including PKM2, PGM, CKM and ALDO. Also binds PLG and troponin, in vitro. Interacts with PNKD By similarity.
Subcellular location	Cytoplasm. Note: Localized to the Z line. Some colocalization with CKM at M-band By similarity.
Tissue specificity	The alpha/alpha homodimer is expressed in embryo and in most adult tissues. The alpha/beta heterodimer and the beta/beta homodimer are found in striated muscle, and the alpha/gamma heterodimer and the gamma/gamma homodimer in neurons. In striated muscle, the fiber-type order of ENO3 expression is IIB > IIX > IIA > I. Ref.10
Developmental stage	During ontogenesis, there is a transition from the alpha/alpha homodimer to the alpha/beta heterodimer in striated muscle cells, and to the alpha/gamma heterodimer in nerve cells. In hindleg muscle, first expressed at E15 after which, levels increase sharply between E15 and E17. A steep prenatal rise in expression accompanies the formation of secondary myofibers and the development of innervation. High levels continue throughout newborn and adult stages. Beginning at postnatal day 5, a second sharp increase in expression correlates with the definitive specialization of the myofibers. Later in development, mainly expressed in fast-twitch fibers. In cardiac muscle, first expressed in the embryo in the cardiac tube. Ref.8 Ref.9
Induction	Levels decrease in degenerating myofibers, and increase with their regeneration.
Sequence similarities	Belongs to the enolase family.
